安装和配置nginx

Nginx 安装

系统平台:CentOS release 6.6 (Final) 64位。

一、安装编译工具及库文件

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

二、首先要安装 PCRE

PCRE 作用是让 Nginx 支持 Rewrite 功能。

1、下载 PCRE 安装包,下载地址: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

[root@bogon src]# cd /usr/local/src/

[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

 2、解压安装包:

[root@bogon src]# tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

[root@bogon src]# cd pcre-8.35

4、编译安装 

[root@bogon pcre-8.35]# ./configure

[root@bogon pcre-8.35]# make && make install

5、查看pcre版本

[root@bogon pcre-8.35]# pcre-config --version

 

安装 Nginx

1、下载 Nginx,下载地址:https://nginx.org/en/download.html

[root@bogon src]# cd /usr/local/src/

[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

 2、解压安装包

[root@bogon src]# tar zxvf nginx-1.6.2.tar.gz

3、进入安装包目录

[root@bogon src]# cd nginx-1.6.2

4、编译安装

[root@bogon nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35

[root@bogon nginx-1.6.2]# make &&  make install

5、查看nginx版本

[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

 

 到此,nginx安装完成。

 


 

Nginx 配置

创建 Nginx 运行使用的用户 www:

[root@bogon conf]# /usr/sbin/groupadd www 

[root@bogon conf]# /usr/sbin/useradd -g www www

配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容

[root@bogon conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf

 

user www www;

worker_processes 2; #设置值和CPU核心数一致

error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别

pid /usr/local/webserver/nginx/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.

worker_rlimit_nofile 65535;

events{

  use epoll;

  worker_connections 65535;}

http{

  include mime.types;

  default_type application/octet-stream;

  log_format main  '$remote_addr - $remote_user [$time_local] "$request" '

               '$status $body_bytes_sent "$http_referer" '

               '"$http_user_agent" $http_x_forwarded_for';

  #charset gb2312;

     

  server_names_hash_bucket_size 128;

  client_header_buffer_size 32k;

  large_client_header_buffers 4 32k;

  client_max_body_size 8m;

     

  sendfile on;

  tcp_nopush on;

  keepalive_timeout 60;

  tcp_nodelay on;

  fastcgi_connect_timeout 300;

  fastcgi_send_timeout 300;

  fastcgi_read_timeout 300;

  fastcgi_buffer_size 64k;

  fastcgi_buffers 4 64k;

  fastcgi_busy_buffers_size 128k;

  fastcgi_temp_file_write_size 128k;

  gzip on; 

  gzip_min_length 1k;

  gzip_buffers 4 16k;

  gzip_http_version 1.0;

  gzip_comp_level 2;

  gzip_types text/plain application/x-javascript text/css application/xml;

  gzip_vary on;

 

  #limit_zone crawler $binary_remote_addr 10m;

 #下面是server虚拟主机的配置

 server

  {

    listen 80;#监听端口

    server_name localhost;#域名

    index index.html index.htm index.php;

    root /usr/local/webserver/nginx/html;#站点目录

      location ~ .*\.(php|php5)?$

    {

      #fastcgi_pass unix:/tmp/php-cgi.sock;

      fastcgi_pass 127.0.0.1:9000;

      fastcgi_index index.php;

      include fastcgi.conf;

    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$

    {

      expires 30d;

  # access_log off;

    }

    location ~ .*\.(js|css)?$

    {

      expires 15d;

   # access_log off;

    }

    access_log off;

  }

}

检查配置文件nginx.conf的正确性命令:

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

 

 

 

 


 

启动 Nginx

Nginx 启动命令如下:

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx

 

 


 

访问站点

从浏览器访问配置的站点ip:

 

 

 


 

Nginx 其他命令

以下包含了 Nginx 常用的几个命令:

/usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件

/usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启

Nginx/usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx

 

安装后的优化

11.编写nginx服务脚本

vim /etc/init.d/nginx

内容全部替换:

#!/bin/bash

# chkconfig: 2345 99 20

# description: Nginx Server Control Script

PROG="/usr/local/nginx/sbin/nginx"

PIDF="/usr/local/nginx/logs/nginx.pid"

case "$1" in

start)

$PROG

;;

stop)

kill -s QUIT $(cat $PIDF)

;;

restart)

$0 stop

$0 start

;;

reload)

kill -s HUP $(cat $PIDF)

;;

*)

echo "Usage: $0 {start|stop|restart|reload}"

exit 1

esac

exit 0

12.给该文件添加执行权限

chmod +x /etc/init.d/nginx

13.通过脚本可以启动、停止、重启、重载服务器

chkconfig --add nginx

chkconfig nginx on

chkconfig --list nginx

14.配置nginx.conf文件

vim /usr/local/nginx/conf/nginx.conf

内容全部替换:

user  nginx nginx;

worker_processes  2;

worker_cpu_affinity 01 10;

worker_rlimit_nofile 102400;

error_log  logs/error.log;

pid        logs/nginx.pid;

 

events {

    use epoll;

    worker_connections  4096;

}

 

 

http {

    include       mime.types;

    default_type  application/octet-stream;

 

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for"';

 

    access_log  logs/access.log  main;

    sendfile        on;

    keepalive_timeout  65;

 

    server {

        listen       80;

        server_name  localhost;

        charset utf-8;

 

        location / {

            root   html;

            index  index.html index.htm;

        }

#error_page  404              /404.html;

 

        # redirect server error pages to the static page /50x.html

        #

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

            root   html;

        }

    }

}

15.修改nginx.conf主配置文件

vim /usr/local/nginx/conf/nginx.conf         添加内容:(第一个location下)

location /status {

stub_status on;

access_log off;

        }

实现访问IP地址下的ststus可以显示nginx界面

16.重启服务

systemctl restart nginx   

**若已经安装nginx,要隐藏版本号

vim /usr/local/nginx/conf/nginx.conf

添加内容:

server_tokens off;

重启服务

/usr/local/nginx/sbin/nginx -t

Killall -1 nginx

测试:IP地址/任意字符
